Referring to FIG. 4, FIG. 4 is a flow chart of a method for determining a quality of question according to an embodiment of present disclosure. As shown in the FIG. 4, the method includes the following steps.

Step 401, extracting a question feature from a user question, and obtaining a basic quality index according to the question feature.

The step of obtaining a basic quality index according to the question feature may include the following steps. Collecting corpus which is labeled, establishing a training model by presenting the corpus with feature, and obtaining the basic quality index by applying the question feature to the training model.

Step 403, obtaining a quality index of the question on each website according to the basic quality index of the question and the matching index of the question with the website.

In an embodiment of present disclosure, obtaining the quality index of question on each website by linear weighting the basic quality index of the question and the matching index of the question with the website.

In another embodiment of present disclosure, the method further includes, posting the question to the website which has a highest quality index of the question.

Further description of present disclosure will be illustrated, which combined with embodiments with detailed embodiments.

The probability of the question which is answered to is defined as the quality of the question in an embodiment of present disclosure. Actually, a quality score of the question includes two parts. One part is a basic quality score of the question. In another word, the basic quality score of the question is the basic quality index of the question. The other part is a matching degree score of the question and each website. In another word, the matching degree score of the question and each website is the matching index of the question and each website. The quality score of the question is a linear weighting summation of the basic quality score and the matching degree score. In another word, the linear weighting summation is the quality index of the question.

A measurement of the basic quality score of a question is mainly based on a basic feature of the question, such as clarity. The basic quality score may divide the questions into good classification and a bad classification in a typical automatically classifying method.

An automatically classifying method includes a training process and a forecasting process. The training process includes, collecting amount of labeled corpuses corresponding to a classification system, establishing a model by representing the labeled questions in a feature method, and forming a classifier. The training process includes expressing a new question by feature, inputting the new question to the classifier, and outputting a classification of the new question.

The method of labeling the corpus includes determining whether the question is a high quality question according to a preset rule. The high quality question is a clearly described and sincere tone of question. And the high quality question does not include an inappropriate content. The question is determined to meet all basic conductions and at least one attractive conduction.

The basic conductions may be the following conductions such as not including meaningless content, clearly description, and without typos, etc. The attractive conductions may be requirement explicitly, widely used, and huge number of the similar questions, etc.

The features of a negative example may be, such as, can not form a question, too subjective, too broad, typos, and with a character hard to understand, etc.

A set of features may be designed for describing the question. Because there is only a title of a text, attributions of a text may be used for describing the question. The attributions may be length of a text title, a characteristic whether a word is a hot word, etc. Further description of setting a set of feature will be illustrated, which combined with a table 1.

The table 1 is a characteristic table for basic grading of question.

TABLE 1 NO. Feature Scope 1 length character length 2 participle number number 3 non-repeat word number number 4 question word include or not 5 verb number number 6 noun number number 7 question mark number number 8 exclamation mark number number 9 meaningless word number number 10 non-key word number number 11 character number number 12 signal word number number 13 Martian character number number 14 English term number number 15 solid word number 16 emotion term number number 17 negative word include or not 18 regional term number number 19 name term number number 20 emergency degree of the answer integer 21 gratitude word number number 22 hot word include or not 23 new word include or not 24 numeral word include or not 25 negative word (junk word) include or not 26 auxiliary word include or not 27 time word (and other time property word) include or not

In the typical automatically classifying method, the method includes training the data and generating a model, applying the classifier to other unlabeled questions, and dividing the questions into a good classification and a bad classification.

In an embodiment of present disclosure, the basic quality score of the question may be obtained depended on the classification of the question. For example, if the question is a question of the good classification, the basic quality score of the question is 0.8. Otherwise, the basic quality score of the question is 0.2.

In other words, the basic quality score of the question can be calculated by the following method.

If the question is a question of the bad classification, then, QuestionScore (question)=0.2.

If the question is a question of the good classification, then QuestionScore (question)=0.8.

The method of calculating the basic quality score of the question is described in detail above. The method of calculating the matching degree score of the question and each website is described in detail as the follows. The matching degree score of the question and each website is the matching index of the question and each website.

In detail, a question model and a website model are described in the same model in order to measure a matching degree between the question and the website. In the embodiment of present disclosure, the question model and the website model are established by a classifying method. If a classification number of the models is n, the question model and the website model is a n-dimensional vector, and each element of the n-dimensional vector is the probability of each classification.

The question model is P(question)=P (x1, x2, . . . , xn). Hereinto, x1, x2, . . . , xn are the probabilities of the questions belong to the classifications of the website.

The website model is P(site)=P(y1, y2, . . . , yn). Hereinto, y1, y2, . . . , yn are the probabilities of the posts of the websites.

A calculating method of the question model is mainly a textual automatically classifying method. For example, a classification probability is obtained by automatically classifying the text by using a simple Bayes theorem or a logic regression.

A calculating method of the website model includes calculating a classification probability vector of each website according to a classification ratio of each question in the website. For example, there are two classifications in a website, and the two classifications are sport classification and digital technology classification. A question number of the sport classification is 20, and a question number of the digital technology classification is 80, then the website model is (probability of sport classification, probability of digital classification)=(0.2, 0.8). The classification of each question can be determined by the textual automatically classifying method.

The method of calculating the matching degree between the question and the website by calculating the similarity of a classification probability model of the question and a classification probability model of the website. Calculating the similarity of the classification probability model of the question and the classification probability model of the website can use a cosine distance similarity method. An expression of the similarity can be illustrated as follows.

Similarity=sim(P(question),P(site))=cos<P(question),P(site)>

Further description of calculating of the mating degree will be illustrated, which combined with a simply example.

In the example, a website site1 is a forum about computer. There are 100 posts in the forum, 90 posts are about computer products, and the other 10 posts are about games. The website model is illustrated as follows.

P(site1)=P(computer products, games)=(90/100, 10/100)=(0.9,0.1)

If there are three questions and the three questions are question1, question2, and question3.

Question1=“Does Lenovo has any good computer products recently?”

Question2=“Why the Lenovo Y470N is influent when play the WOW of WARCRAFT?”

Question3=“What is the weather like today in Beijing?”

Obtaining the question models of the above three questions by using the textual automatically classifying method.

P(question1)=P(computer products, games)=(1,0).

P(question2)=P(computer products, games)=(0.5,0.5).

P(question3)=P(computer products, games)=(0,0).

Calculating the matching degrees of the three questions and the website by using the cosine distance similarity method.

The matching degree of the question1 and the website site1 is: sim(P(question1),P(site1))=cos<(1,0), (0.9, 0.1)>=[(1*0.9)+(0*0.1)]/[sqrt(1*1+0*0)*sqrt(0.9*0.9+0.1*0.1)]=0.9939. Hereinto, the sqrt means a square-root algorithm.

Using the same method, the matching degree between the question2 and the website site1 is 0.7809, and the matching degree between the question3 and the website site1 is 0.

In the website of large scale, the question number may be hundreds of thousands every day. However, in the website of small scale, the question number may be only dozens every day. Even if the matching degree of one question and one website is high, but the website is a website of small scale, the probability of answering the question may be low.

In another embodiment of present disclosure, an activity index of the website is introduced to determine an activity of the website. The activity index of the website is mainly measured by the number of the questions posted on the website every day. Then the number of the question is processed by the normalization process. Further description is illustrated as the follows.

If the question number of all websites connected with the system every day is M, the question number of one website is N, the activity index of the website is defined as N/M. The activity index of the website is represented by character Liveness.

Livenness=N/M

A matching score of the question and the website equals a product of the matching degree and the activity. That is: SiteSore(question, site)=Similarity*Livenness

A final score of the question equals the weighted summation of the basic quality score of the question and the matching score of the question and the website. In the embodiment, the final score equals a linear weighted summation of the basic quality score of the question and the matching score of the question and the website.

FinalScore(question, site)=a*QuestionScore(question)+(1−a)*SiteScore(question, site)

Hereinto, 0<a<1, and a is a weight which is configured to measure the basic quality score of the question and the matching score of the question and the website. A value of a may be 0.6.

To a question, a table of the quality score of the question in different website is obtained. Then the question is posted to the website which has the highest quality index of the question.

If the question includes more information, such as a description of the question, the information can be used in calculating the basic quality score of the question. Thus, an accuracy of calculating the basic quality score of the question is improved. The classification probability model is used in the above embodiments of present disclosure. But, the invention is not limit to the classification probability model, other models can be used for describing the website in another embodiment of present disclosure. For example, the websites can be divided into more multi-classifications. Or the same description can be used for the questions when calculating the matching degree of the question and the website.
